Abstract (en)

Embodiments of the present disclosure disclose an expansion connector for connecting square tubes comprising a base (1) and a square column (2) movably connected to the base (1). The square column (2) is movable relatively to an end of the base (1). A first expansion piece (3) and a second expansion piece (4) are sleeved on the square column (2). The first expansion piece (3) has a first insertion groove (5) on a side. The first expansion piece (3) has a first insertion piece (6) on one end. The first insertion piece (6) has a first bending portion (7) which is in contact with the square column (2). The second expansion piece (4) has a second insertion groove (8) on a side. The second expansion piece (4) has a second insertion piece (9) on one end. The second insertion piece (9) has a second bending portion (10) which is in contact with the square column (2). The four sides of the expansion connector for connecting square tubes are all expanded to contact the inner sides of the square tubes. In this way, the connection between the expansion connector and the square tubes becomes firmer to avoid the disengagement of the square tubes.
